Step Command Remarks
3. (Optional.) Add an OUI
address for voice packet
identification.
voice-vlan mac-address oui mask
oui-mask [ description text ]
By default, system default OUI
addresses exist. For more
information, see
Table 12 .
4. Enter Layer 2 Ethernet
interface view. interface interface-type
interface-number
N/A
5. Configure the port to operate
in manual voice VLAN
assignment mode. undo voice-vlan mode auto
By default, the manual voice VLAN
assignment mode is disabled.
6. Assign the access, trunk, or
hybrid port in manual voice
VLAN assignment mode to the
voice VLAN.
• For the access port, see
"Assigning an access port to a
VLAN."
• For the trunk port, see
"Assigning a trunk port to a
VLAN."
• For the hybrid port, see
"Assigning a hybrid port to a
VLAN."
After you assign an access port to
the voice VLAN, the voice VLAN
becomes the PVID of the port.
7. (Optional.) Configure the
voice VLAN as the PVID of the
trunk or hybrid port.
• For the trunk port, see
"Assigning a trunk port to a
VLAN."
• For the hybrid port, see
"Assigning a hybrid port to a
VLAN."
This step is required for untagged
incoming voice traffic and
prohibited for tagged incoming
voice traffic.
8. Enable the voice VLAN
feature on the port.
voice-vlan vlan-id enable
By default, the voice VLAN feature
is disabled.
Enabling LLDP for automatic IP phone discovery
The device can automatically discover the peer through LLDP, and exchange LLDP TLVs with the peer. If
the LLDP System Capabilities TLV received on a port indicates that the peer can act as a telephone, the
device sends an LLDP TLV with the voice VLAN configuration to the peer.
When the IP phone discovery process is complete, the port will continue the following voice VLAN
configuration:
• Join the voice VLAN.
• Increase the transmission priority of the voice traffic sent from the IP phone.
To ensure that the IP phone can pass authentication, the device will add the MAC address of the IP phone
to the MAC address table.
Configuration prerequisites
Before you enable LLDP for automatic IP phone discovery, complete the following tasks:
• Enable LLDP globally and on ports.
• Complete voice VLAN configurations.
